Answer:

-29

Step-by-step explanation:

replace the variables with the numbers provided. m = -4 so replace the m in the equation with -4:

3 - (-4)n

same thing with the n.  n=-8 so replace the n in the equation with -8:

3 - (-4)(-8)

and then all you have to do after that is solve it using PEMDAS

multiply -4 and -8 first:

3 - 32

then solve 3-32 and you end up with -29.

What is the slope of the line that passes through the points (-9, -9) and (-9, -7) Write in simplest form.
dimaraw [331]

Answer:

Undefined slope, vertical line

Step-by-step explanation:

Slope = \frac{y_{2} -y_{1}}{x_{2}-x_{1}}

Slope = \frac{-7 -(-9)}{-9-(-9)} = \frac{-7+9}{-9+9} =\frac{2}{0} = Undefined

Since the slope is undefined, you would have a vertical line.

In an ordered pair,the x-coordinate represents the number of hexagons and the y-coordinate represents the total number of sides.
Novosadov [1.4K]
The y-coordinate would be 42.

Hexagons have 6 sides.  The x-coordinate is the number of hexagons; since our x-coordinate is 7, that means 7 hexagons.  

The y-coordinate is the total number of sides.  7 hexagons * 6 sides per hexagon = 42 sides.

Item 1<br> Find the dimensions of the square.<br><br> Area = 441 cm²
mafiozo [28]

Answer:

21 cm by 21 cm

Step-by-step explanation:

The formula for the area of a square is A = x^2, where x is the length of any one side of the square.  Here,

441 cm² = x²

This actually has two roots:  {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.

The dimensions of the square are 21 cm by 21 cm.
